Mountain Building Lesson Flyswatter Game

1.

Deformation – the process by which rocks change shape when under stress

2.

Stress – amount of force per unit area that is placed on an object

3.

Tectonic plate – a block of lithosphere that consists of crust and the outermost part of the mantle

4.

Low temperatures – What temperatures can make materials more brittle?

5.

Higher temperatures – What temperature allows rock to bend?

6.

Break – If stress becomes too great, or is applied quickly the rocks can _____?

7.

Folds – When rocks bend ________________ form.

8.

Fault – When rocks break ________________ form.

9.

Folds – Bends in the rock

10.

Syncline – a downward fold (use foam to show a syncline)

11.

Anticline – An upward fold (use form to show an anticline)

12.

On the outside of the fold – Where are the youngest rocks in an anticline found?

13.

On the inside of the fold – Where are the youngest rocks in a syncline found?

14.

Fault –Crack that forms when large blocks of rock break and move past each other.

15.

Fault blocks – blocks of rock on either side of the fault

16.

Fault plane – where two fault blocks meet

17.

Hanging wall – the block of rock above the fault plane

18.

Footwall – the block of rock below the fault plane

19.

Shearing – stress that pushes rock in parallel by opposite directions

20.

Strike-slip – The type of fault where the fault blocks move past each other horizontally

21.

San Andreas Fault – an example of a strike-slip fault

22.

Tension – stress that stretches or pulls rock apart

23.

Normal Fault – The type of fault where the hanging wall moves down relative to the footwall.

24.

Compression – stress that squeezes or pushes rock together

25.

Reverse Fault - The type of fault where the hanging wall moves upward relative to the footwall.

26.

Uplift – a process that can cause land to rise

27.

Folded Mountains – mountains that form when rock layers are squeezed together and pushed upward

28.

Convergent Boundaries – Folded mountains usually form at this type of boundary

29.

Appalachian Mts. – an example of folded mountains

30.

Volcanic Mts. – mountains that form when melted rock erupts onto Earth’s surface

31.

Mt. St. Helens – an example of a volcanic mountain

32.

Fault-Block Mountains – mountains that form when tension makes the lithosphere break into many normal faults

33.

The Teton Mts. – an example of fault-block mountains
